15\times 1500-1500=150x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 15x, the least common multiple of x,15x.
22500-1500=150x
Multiply 15 and 1500 to get 22500.
21000=150x
Subtract 1500 from 22500 to get 21000.
150x=21000
Swap sides so that all variable terms are on the left hand side.
x=\frac{21000}{150}
Divide both sides by 150.
x=140
Divide 21000 by 150 to get 140.
